Liposarcoma of the spermatic cord is a malignant tumor so rare that there are less than 200 cases reported in the literature worldwide. Liposarcoma is a malignancy which originates from fat tissue. Although only 3%-7% of all paratesticular sarcomas primarily arise from structures of the spermatic cord, clinical significance of these tumors must not be neglected because they are often preoperatively misdiagnosed. A 66-year-old male presented with a painless swelling on the left side of the scrotum. Local examination revealed a solid, smooth, limited mass of approximately 4x3 cm in the left side of the scrotum. Tumor markers were within the reference range. Ultrasound examination showed a solid, clearly limited non-homogeneous mass of 40x20 mm localized in the left spermatic cord. Magnetic resonance imaging showed an expansive mass measuring 60x85x60 mm in the left inguinoscrotal region without propagation into the abdominal cavity. Both testicles and epididymides appeared normal on magnetic resonance examination and no locoregional enlarged lymph nodes were seen. The patient was treated operatively with radical inguinal orchiectomy. In conclusion, liposarcomas of the spermatic cord are extremely rare neoplasms that clinically present as slow-growing, painless, palpable inguinal or scrotal masses. Radical orchiectomy with high ligation of the spermatic cord and wide excision of the surrounding soft tissues within the inguinal canal remains the gold standard treatment option. Recurrence of the disease is frequent even several years after primary therapy, therefore long-term follow-up is mandatory.

Total androgen blockade and LH-RH agonists are more effective in lowering testosterone values (to castration values) compared to the antiandrogen monotherapy, where testosterone values stay above the castration level. This therapy approach has advantages, since it decreases testosterone values providing better therapy response. There is a difference in testosterone values, but not significant, when total androgen blockade and monotherapy with LH-RH agonists are administered. Registered lower basal values of LH in all patients with prostatic cancer open the possibility to introduce LH as a new additional, significant marker in diagnosis of this neoplasm.

Introduction. In recent years, there has been a growing global trend in the number of people with pathogens of sexually transmitted infections. There is a worldwide lack of data on the prevalence and incidence of sexually transmitted infections in the general population, especially among the high school students. Material and Methods. We conducted a cross sectional study on attitudes and knowledge of young people about sexually transmitted infections. The survey population included young people aged 14 to 20 years attending a high school in the city of Novi Sad. The data were collected through a questionnaire. Results. The percentage of students with signs and symptoms of sexually transmitted infections was higher among the students who did not use a condom during the last sexual intercourse compared to the students who used a condom. Conclusion. Young people engaging in risky sexual behavior showed better knowledge about sexually transmitted infections in comparison to young people who did not engage in risky sexual behavior.
